How do we know that salvation is eternally secure?

The security of a believer’s salvation is anchored in the unchangeable nature of God's promises. John 10:28-29 affirms that no one can pluck God's elect from His hand, emphasizing the certainty of our preservation. Furthermore, Romans 8:38-39 declares that nothing can separate us from the love of God in Christ Jesus. This assurance is bolstered by the seals of the Holy Spirit (Ephesians 4:30), which signifies that we are marked as God’s own until the day of redemption. Thus, our security does not depend on our performance but solely on the faithfulness and power of God to fulfill His promises.
